Tom Kington “Secret stash of 100 'Caravaggio sketches' found in Milan castle” http://www.guardian.co.uk/artanddesign/2012/jul/05/caravaggio-discovery-milan-castle
ミラノのCastello Sforzescoにてカラヴァッジオ（Michelangelo Merisi da Caravaggio）*1のスケッチ100点が発見された。画家Simone Peterzano*2のアーカイヴの中から。少年時代のカラヴァッジオは1584年から1588年まで彼の工房の徒弟だった。
Conconi Fedrigolli said the 100 sketches were evidently not the work of Peterzano. "The work of the maestro is extremely fussy and precise, whereas the work of the adolescent Merisi, just like his mature work, is powerful,realistic, but still messy," she said. The sketches reveal the young Merisi made mistakes, she added. "Some errors were so deep-seated they reappear years later in more celebrated paintings, including his noses of cows and his heels, which he never mastered."
